  1. The skin condition variables measured in this study for the “computer group” (CG) and the “non-computer group” (NCG) are listed in the left column, with the associated statistical analysis data characteristics. Results of parametric analysis are given by mean ± standard deviation (SD). Results of non-parametric data analysis are given by median ± interquartile range (IQR) and indicated by *. The types of queries collected are indicated as either continuous, binary, or ranking. Significance is shown in italic (<0.05) or bold italic (approaching 0.05)
